Correct: 1, 3, and 4.

Explanation: The nonrestrictive clause "who won a prestigious art award last year" must be set off from the rest of the sentence. That can be done with parentheses (1), commas (3), or em dashes (4). Sentence 2 misplaces the dashes so the clause boundaries are wrong; sentence 5 omits the required punctuation (commas/dashes/parentheses).
